\ Application me@ June 1s, 1927. serial N0.`199,78s.

This invention relates to an improved arrangement, in a closet basin,for prevent-ing rats entering dwellings through said basin and at thesame time for exterininating said dangerous animals.

From known arrangements of similar kind, the improved arrangement isdistinguished by the rear outlet end o1 the closet basin, that is closedtoward the 't'ront end by means ot a non-return flap7 Jforming at itsupper part a segarate chamber 'for the reception of rat poison and of abait for the rats, said chamber being Fitted. with a removable coverpermitting an easyy access thereto from outside. I

The accompanying drawing illustrates, lby way ot example, a closet basinin a vertical longitudinal section embodying the improved arrangement.

The closet basin a has as usual a rear 0utlet end closed toward thefront end of the basin by means of a non-return flap c vand joined at lto the branch e of a waste-pipe.

Said outlet end Z) terms at its upper part a chamber g that issubdivided by meansr of a rib f, so that above the latter a separatecompartment U for the reception of rat poison is created. At the top andrear ot said compartment a. separate receptacle h is arranged tor thereception of a baitfor the rats, said bait being so located in thereceptacle that cannot be reached by the rats.

Atits upper end, the `poison compartment j) is Closed by means of aremovable cover z', which for instance engages at the front end below aprojection k ot the closet basinv and at its hook-shaped rear end Zover'the outwardly projecting upper edgem of the rear wall n ot saidpoison compartment while a pin o secures it against' lateraldisplacement. A lifting ot the cover in upward direction from inside thecompartment by the' rats isthereby made impossible.

Due to the particular arrangement of the bait receptacle at the top andrear of the f poison compartment, the rats are always compelled to enterthe latter prior to their l trying toV get at the bait.

What I claim, is

1. In a closet basin, the combination with the rear outlet end of the'latter closed toward the front end by means of a non-return Hap, of aseparate chamber in the upper part ot'- and accessible from said rearoutlet end serving 'for the reception oi rat poison and otl a bait forthe rats entering said rear outlet end, and a removable cover for saidchan'iber. t

2. In an arrangement specified in claim l, a separate bait receptacle atthe top and rear of said chamber.

In testimony whereof I have hereunto set my hand.
